Title: Video monitoring and conferencing system
Inventor: WASHINO KINYA
IPC: H04N7/10
Filed: 1996-04-04
Abstract: A PC-based system (220) for monitoring and storing representative images from video cameras (252, 254) may be utilized for security and other monitoring applications.     Camera inputs from digital or analog sources are individu-ally and independently digitized and displayed at a first set of image sizes, sampling rates, and frame rates, and may be stored in digital form on various recording media at a sec-ond set of image sizes, sampling rates and frame rates, and these two sets of sizes and rates may or may not be identi-cal. Provisions are included for adding detection or alarm systems which will automatically alter image size, sam-pling rate and/or frame rate of an individual input source, or activate other physical responses. In addition to security system monitoring, further applications of the invention are disclosed for process monitoring in manufacturing environ-ments and also for applications in videoconferencing.
Patent CA-2215807-A1 (CA)
Inventor: FERNALD KENNETH WILSON
IPC: H03M1/00
Filed: 1996-03-28
Abstract: A method and apparatus is disclosed for use in an implantable device that includes an analog-to-digital converter (ADC) for converting electrograms (such as EKG signals) into digital codes that can be stored in memory. The ADC  constructed according to the present invention is capable of achieving considerable power savings by minimizing the number of clock cycles required to determine the correct digital code for a particular sample point on the electrogram signal, thus making it possible to turn off some or all of the ADC  logic during idle periods. The ADC includes prediction logic that provides a starting point for subsequent searching for the correct digital code value.  The prediction logic receives recent code conversions values which it uses to predict the current digital code value. This predicted digital code is converted to an analog value and compared with the actual electrogram voltage to determine if the prediction is above or below the correct code representation. Next, the ADC adds (or subtracts) a constant value (C) to (or from) the predicted code and compares the result to the actual electrogram voltage. If the ADC determines that the predicted value is within the constant value (C) of the correct digital code, then the ADC counts in the proper direction (determined by the first comparison) until the comparator changes output state, indicating that the correct code is found. If the ADC determines that the predicted value is not within the constant value (C) of the correct digital code, then the successive approximation logic is enabled and used to find the correct code. By selecting the constant value (C) to be approximately equal to the number of clock cycles required for the successive approximation circuitry to determine the correct code, the present invention, on average, can determine the correct code significantly faster than can be obtained using only successive approximation logic.

Title: Linked caches for context data search
Inventor: BERMAN STUART
IPC: G06F12/08
Filed: 1996-05-24
Abstract: A method and apparatus for linking two independent caches which have related information stored therein. Each unit of information stored in a first cache memory (103) is associated with one unit of information stored in the second cache memory (109). Each unit of information stored in the first cache memory includes a pointer or index to the associated information unit in the second cache memory. Each information unit stored in the second cache is only stored once, regardless of the number of units in the first cache that are associated with a particular unit within the second cache. Therefore, even if more than one unit of information within the first cache memory is associated with the same unit of information within the second cache memory, that unit of information stored in the second cache memory is only stored once.

Title: Oil seed protein extraction
Inventor: MURRAY EDWARD D
IPC: A23J1/14
Filed: 1997-01-29
Abstract: Protein isolates having a high protein content and low residual fat content are provided in substantially non-denatured form by extracting an oil seed meal having a significant fat content, particularly canola meal, with an aqueous food grade salt solution to cause solubilization of protein and fat in the oil seed meal and form an aqueous protein solution. Fat is removed from the aqueous protein solution by chilling the aqueous protein solution and removing the fat which separates. The protein concentration of the defatted protein solution is increased while the ionic strength is maintained substantially constant. A further fat removal operation may be carried out on the concentrated protein solution followed by dilution to an ionic strength below about 0.2 to cause the formation of discrete protein particles in the aqueous phase in the form of protein micelles. These protein micelles are settled to form a mass of aggregated protein isolate in the form of an amorphous, sticky gelatinous, gluten-like protein micellar mass, which is separated from the supernatant and dried to a proteinaceous powder.
